5.6 SETTING THE COFFEE VOL-
UME PORTIONS
(volumetric
portion control)
A flow meter allows the machine to calculate
the precise coffee volume you would like from
the single or double porta filter. (Generally 25
to 30ML from the single porta filter and 50 to
60 ML from the double porta filter). When you
are sure the grind setting is correct you can
set the flow meter.
It is important to understand that
the volumetric portion control
will differ between each pressure
profile. The flow meter will count
total water volume irrespective of
the time it may take.
Example; Pump pressure of 9 bar
over 30 seconds will yield a different
total volume than 5 bar over the
same 30 seconds.
